John grinned with glee as he showed off a
healthy head full of hair, completing his look with a smart black suit,
shirt, tie and leather shoes.

Kelly meanwhile looked fabulous in a black dress and stilettos, and seemed thrilled to be mixing with her fellow high-profile worshipers.

Also in attendance was American Hustle actor Michael Pena and Parenthood favourite Erika Christensen

John, who has been practicing since 1975, has praised the religion in the past, and is quoted as saying on its website: 'I have a wonderful child and a great marriage because I apply L. Ron Hubbard’s technology to this area of my life.

'I would say that Scientology put me into the big time. '

Secret of his success: The Saturday Night Fever hunk as credited his faith for personal and professional prosperity

According to its website, the Celebrity
Centre was set up by the religion's founder L. Ron Hubbard, who was also a science fiction author, for 'the artists,
politicians, leaders of industry, sports figures and anyone with the
power and vision to create a better world.'

Meanwhile John is getting ready to take on his former pilot in court.

An appeals court ruled Douglas Gotterba
is allowed to make a case that he has no confidentiality agreement
covering his employment with the actor.

The pilot wants to give a revealing account of his time working for Travolta's airline company Alto, and was given approval by a California court last month to make his case.

Cult classic: The Church Of Scientology Celebrity Centre has been a Hollywood landmark since 1969.

Gotterba, who claims to have had more than just a business relationship with the star, has been trying to prove the agreement is invalid, after Travolta's attorney made a cease-and-desist order.

An attorney for Travolta said: 'While we believe the court should have thrown out Gotterba’s lawsuit at the outset, ultimately, he will not prevail on his claim.

'Gotterba points to an unsigned draft agreement, which he now claims is the controlling document in the case, yet he attached as an exhibit to his own complaint the final version of the contract that he signed barring his claim. We are very confident that in the end we will prevail in the action.'
